Does the engine crank with no start?

Or does nothing happen when the press the start button?

Turn out to be the F79 fuse burned
F79 Crankcase breather heating
Oxygen sensor heating

After change the fuse only the cylinder 4 error code 2756 remain
so I check the ignition coil of cylinder 4 first
the PLUG HOUSING (Mfg Part # 12527508154) of the ignitioncoil was burned out
after change the PLUG HOUSING and F79 Fuse and Ignition Coil
no problem with the start
but still unknowing why the plug housing will burned out????
